You kicked off the runs and went to bed. The morning ritual is scrolling transcripts and hoping nothing broke. RunReceipts replaces the hope: every run leaves a receipt, the diff, the checks that actually executed, exit codes included, and the receipt gets graded before the work counts.

A system reporting on itself is not evidence. That rule was the day job. Now it reads your agents' homework.
Paste a run receipt, or point at a public GitHub PR, and get the structural grade in milliseconds: what changed, what ran, what passed. Same receipt in, same grade out, forever.
One agent lying politely is catchable by eye. Eight in parallel is not. Most of what people call verification is scrolling until you feel ok: vibes with a progress bar. The transcript is the agent's story about what it did. The diff is what it did.
Deterministic structural checks, every flag citing a principle. A success claim with no passing check that plausibly exercises it gets flagged the moment it lands, not three days later in production.
A check without an exit code is a claim that a check ran, not evidence that it did.
A second pass judges the receipt against your original spec, and only that. An agent reading its own transcript inherits its own optimism. This one never gets the chance.
“The diff matches the spec's error-path requirement, and the passing tests exercise it. But the claim says ‘all tasks’ and the receipt only evidences one. Ask the agent for receipts on the other three.”
When every run needs a machine-checkable definition of done, you find out fast which of your tasks were actually vibes. Finding that out before the overnight run, not after, is a feature.
The free grader checks structure. The pass adds judgment: a fresh-context verifier reads the receipt against your spec and tells you, in plain text, whether the run earned its “done” and what to demand from the agent when it didn't.
